Abstract
The invention discloses a magnetic ferrous powder which comprises the following components in part by weight: 3 to 9 parts of polypropylene, 4 to 10 parts of ferrous powder, 3 to 10 parts of polyethylene fiber, 2 to 7 parts of sodium perborate monohydrate, 4 to 7 parts of siloxane, 1 to 7 parts of calcium chloride, 7 to 9 parts of potassium pyrosulfate, and 4 to 7 parts of rubber resin. The magnetic ferrous powder has the advantage of higher magnetic powder flux, and the prepared magnet is long in service life and has no cracks.
Description
Technical field
The present invention relates to a kind of magnetic powder field, be specifically related to a kind of high-effect and can increase the magnetic powder of magnetic flux.
Background technology
The common magnetic flux of existing magnetic powder manufacturing magnet out is large not, and manufacturing magnet out has slight crack because anti-pressure ability is relatively poor easily in the process of making.
Summary of the invention
Goal of the invention: the objective of the invention is in order to remedy the deficiencies in the prior art, it is a kind of high-effect and can increase the magnetic powder of magnetic flux that purpose is to provide.
The technical solution used in the present invention: a kind of magnetic powder, described magnetic powder is comprised of each component of following parts by weight: polypropylene 3-9 part, iron powder 4-10 part, polyethylene fibre 3-10 part, monohydrate sodium stannate 2-7 part, siloxanes 4-7 part, calcium chloride 1-7 part, potassium pyrosulfate 7-9 part, rubber resin 4-7 part.
A kind of manufacturing process of magnetic powder, may further comprise the steps: with polypropylene, iron powder, polyethylene fibre, monohydrate sodium stannate part, siloxanes, calcium chloride, potassium pyrosulfate, rubber resin mixes, and is heated to 300-700 ℃ in the heating tower, again rare gas element is poured in the tower, put at last reactor, be down to after the normal temperature, mix and get final product.
Described magnetic powder diameter is 20-40um.
Beneficial effect: the present invention is compared with existing technology, and magnetic manufacturing magnet magnetic flux out is high.
